NSK 21314DK double-row spherical roller bearing with a tapered bore. Bore Diameter: 70 mm. Outside Diameter: 150 mm. Overall Width: 35 mm. Rolling Elements: Spherical Roller. Number Of Rows: 2. Bore Type: Tapered 1:12. Closure Type: Open. The two roller rows run on a common spherical outer raceway, so the inner ring and roller set swivel within the outer ring and the bearing accommodates shaft misalignment and housing deflection under load.
21314 — ISO spherical roller size in the 213 dimension series, 70 mm bore, 150 mm outside diameter, 35 mm width. The 213 series is the narrow, low-section spherical roller family.
D — pressed steel cage with a floating guide ring between the two roller rows.
K — 1:12 tapered bore.
Cage Material: Pressed steel. Cage Type: Pressed, with a floating guide ring. Internal Clearance: CN. Lubricant: grease or oil. The tapered bore lets radial clearance be set by the drive-up distance on a sleeve, so one part covers a range of shaft fits, and the narrow 213 section keeps the axial envelope short where housing width is constrained.
The 1:12 tapered bore mounts on an adapter sleeve whose tapered outside diameter matches the 70 mm bore. The matching NSK sleeve is an H314, taking a KM14 lock nut and an MB14 lock washer on a 60 mm shaft seat.
Unit Quantity: 1 Pc. Number Of Rows: 2.
Other makers’ 21314 tapered-bore bearings share the 70 x 150 x 35 mm size: SKF 21314 EK, FAG 21314-E1-K-TVPB, Timken 21314KEJW33, Koyo 21314RHK, NTN 21314K and NACHI 21314EXK. Internal design, cage and load ratings differ by maker.
